Biology Chapter 18 Practice Test 44 Questions with Verified Answers In the case of E. coli, the bacterium may need to synthesize tryptophan, or its host, a human, may supply all the tryptophan it needs. Why do both bacteria and humans need tryptophan? A) It is an important enzyme in the glycolysis pathway. B) It is one of the 20 amino acids used by all organisms to synthesize proteins. C) It is an important constituent of cell walls in both humans and bacteria. D) Tryptophan induces the ...

Drug Discovery • Unlike small molecule drugs (pharmaceuticals), large molecule drugs (biopharmaceuticals) are mainly protein-based o These protein-based drugs are similar to natural biological compounds found in human body or they're fragments that mimic active part of natural compounds Discovery of Pharmaceuticals commences w/ scanning hundreds of compounds, whether w/ actual materials (irrational approach) or virtual simulations (rational approach) • Pharmaceuticals are new che...

AP Bio Genetics, RNA, and DNA Practice Exam 110 Questions with Verified Answers In his transformation experiments, what did Griffith observe? a. Mutant mice were resistant to bacterial infections. b. Mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic strain can convert some of the living cells into the pathogenic form. c. Mixing a heat-killed nonpathogenic strain of bacteria with a living pathogenic strain makes the pathogenic strain nonpathogenic. d. Infecti...

A virus has been discovered. The virus has no envelope and consists of a helical capsid surrounding its dsDNA genome. During assembly, the pac site of the genome ensures that it is properly packaged by the capsomeres. Which of the following amino acids is/are expected to be on the capsomere domain that interacts with the pac site? A. lysine B. methionine C. glycine D. arginine E. A and D Answer: A and D Explanation: DNA has a negative charge, so positively charged amino acids, such as...
